JERSEY.

Application filed April 14, 1925,. Serial No.

This invention relates to shoe pressing machines and is illustrated asembodied in a socalled automatic leveling machine of the type disclosedin United States Letters Patent No. 1,239,66el, granted Sept. 11, 1917,on the application of WV. 0. Baxter, although the 1nvention in variousaspects is not limited to embodiment in machines of this type.

In leveling machines of this type, the shoe is supported on a last whichrests on a jack comprising a heel post and a toe post or support, and isheld firmly thereon by appropriate mechanism. These supports as a wholeare adjustable to fit the shoe hem-g treated and the jack is rocked backand forth under a leveling roll which exerts a heavy pressure on theshoe.

Y It has been found in leveling shoes on ointed lasts having relativelymovable heel andfore parts, such as hinge lasts, that the bondingmechanism between the last parts is sometimes too weak to take thepressure of the leveling tool and that consequently the pressuresometimes distorts or breaks the last, thus causing damageto the shoebeing treated.

It is a principal object of the present invention to prevent suchdamage, and to this end the invention provides an improved shoe pressingor leveling machine organization 1ncluding a support for the last in theneighborhood ofthe oint between the heel end and the forepart.Preferably this support will be in adition to the heel and for-apart (ortoe) supporting mechanisms heretofore characteristic of levelingmachines. In the embodiment shown, the supporting mechanism com prises afinger arranged to enter a cut or de pression between the last parts, tosupport the last.

In another aspect, the invention provides supportingmeans for a lastbetween its ends constructed and arranged to be automatically positionedand locked in last-supporting po sition, which, although generallyapplicable to pressing or leveling machine organizations of *arioustypes, is very well adapted for use in an automatic roll levelingmachine of the type above referred to. Preferably, and in accordancewith a further feature of the invention, the support for theintermediate or joint portion of the last automatically measures thedistance from its contact point with the last to a member or abutn'lentto NEW JERSEY, A CORPORATION OF NEW snon-rnnssrne MACHINE.

which the pressure imparted by the leveling element to the last istransmitted, thus avoiding the necessity of adjustment for differentstyles and sizes of lasts. Conveniently, and in the disclosed embodimentof the inven tion, the result above stated is accomplished by anorganization in which the finger above referred to is resiliently forcedupwardly to meet the last, and in which the lower end of the finger issupported through a cam which cooperates with it in varying relations,depending on the contour and dimensions of the last. Preferably, also,the cooperation of this cam with the finger is automatic and iscontrolled by the operations of jacking and unjacking the shoe (or last)so that the operator needs to devote no attention whatever to thesupporting means. 7

Another feature of the invention consists in a novel constructionwhereby the last sup porting means is rendered adjustable to contactwith the last in the desired locality, considered longitudinally of thelast. in the illustrated machine which is adapted especially for thetreatment of shoes on hinge lasts of the type having a V out in theirupper surfaces to permit the hinging collapse, the desired result isattained by pivoting the contact member for longitudinal movementrelatively to the last, so that it automatically slides into the V toseat itself in position to support the last in the region of its jointor hinge.

These and other features of the invention comprising certain novelcombinations and arrangements of parts will be understood from thefollowing description of a preferred embodiment thereof selected forpurposes of illustration and shown in the accompanyin drawings, inwhich,

Fig. 1 is a side elevation of the front portion of amachine of the typereferred to.

Fig. 2 is a perspective view of the jack mechanism as seen from theright side.

Fig. 3 is a somewhat enlarged view of the twin mechanism on the otherside of the machine as seen from the left side.

The illustrated jack mechanism in various respects is identical withthat shown in the Letters Patent referred to and reference may be had tosaid Letters Patent for a more complete disclosure of the constructionand operation of parts not fully described herein. The jack as a wholeis oscillated under a leveling roll about the axis of a rock-shaft 12,on which it is mounted, by power-operated mechanism which need not bedescribed in detail since it is fully disclosed in the abovementionedLetters Patent. The roll is supported in a fork 11 which is hinged atits rear end and forced down toward the jack by heavy springs. Theoscillation of the jack follows a cam-controlled cycle, and the jack isautomatically thrown out to unjacking and jacking position at the end ofthe cycle, all of which will be clear by reference to the patent. Thejack consists essentially of a toe post 14 mounted on the shaft 12, anda heel post 16 which is pivoted at 18 to a crank-arm 20 depending fromthe toe post. The relative adjustment of the two posts is effected by ahand-screw 22, extending between the heel post and a lug on the hub ofthe toe post. The jack pin 24 is tilted away from the operator by a rod26 operated by gearing 28 and a wrench-receiving head at 30. The shoe isjacked by placing the jackpin hole of its last on the jack pin 24,adjusting the screw 22 until the toe of the shoe falls properly into thetoe rest 32, and turning the head 30 until the tilting of the jack pinforces the toe of the shoe firmly into the toe rest. All of thismechanism is substantially as shown in the patent referred to.

Pivotally mounted on the heel post 16, and conveniently on the shaft 34of one of the gears 28, is a cam or looking member 86, having adownwardly extending tail 38. A swinging lever is pivoted at 42 at thebottom of the heel post and has a lug 44, arranged to be engaged by thecam 36, which swings around its pivot to contact with the lug in anyposition which the latter may assume. When the jack is swung out anddown toward the operator to jack or unjack a shoe as shown in Fig- 3, afixed bracket 46 on the machine frame contacts with the tail 38 andprevents the cam 36 from following the lug 44, thus stressing a spring48 which tends to throw the cam on to the lug. The lever 40 is then freeto swing in either direction about its pivot 42. The lever 40 isU-shaped and embraces the lower end of the heel post.

On the other end of the lever 40 at 50 there pivoted to the lever thelower end of a rod 52, which slides lengthwise in a guide 54, and isresiliently held in raised position by a spring 56 attached to a lug onthe rod at its lower end. Pivot-ed at 58 to the upper end of the rod 52is a last contacting finger 60, having a spring-pressed pin 62 in itwhich engages a V cut in a lug 63 at the upper end oft-he rod 52 asshown in Fig. 3, to hold the finger resiliently in a mean or standard position.

The machine being in the condition shown in Fig. 3, the operator putsthe shoe on the jack as described above, and the finger contacts withthe last. The last shown has tomatic.

a V out at its hinge joint and the finger automatically enters it andsettles to the bottom of it, rotating about the pivot 58 if necessary.In case the same type of last is to be used exclusively on the machine,the finger will conveniently be made to fit the last in any desirablemanner. As shown, the finger,-by reason of its pivotal mounting at 58,is adapted to cooperate efficiently with any last with a V cut. As thelast settles down on the jack pin, the finger 60 and the rod 52 areforced down against the spring 56 carrying the lever 40 with them, (thecam 36 being inoperative,

as already explained) until the shoe is in.

proper position on the pin. The operator will then swing the heelpost'toward the toe post, if such adjustment is required by the lengthof the shoe, and will lock the shoe in the jack. When the machine isstarted and the jack starts to swing up under the roll 10, as shown inFig. 2, the tail. 38 leaves the bracket 46 and the spring 48 pulls thecam 36 against the lug 44, thus locking firmly the lever 40, rod 52 andfinger 60 against downward movement under the leveling pressure, and thejoint of the last is thus supported firmly against the pressure of theleveling roll, 'so that damage to the'last and consequently to the shoeis prevented. The shaft 34 constitutes an abutment which takes thepressure transmitted from the last through the rod, lever and cam. Itwill be clear that this mechanism comprising 'provision for a variableoperative relation between the cam 36 and the lug 44 constitutes ineffect a measuring means for the distance between the last and theabutment, or a take-up mechanism between. these parts.

It will be clear that the operation of the illustrated supporting deviceis entirely au- It unlocks when the jack swings out to interchange shoesand locks as it swings back to operative position and requires noattention whatever from the operator.
